Thanks @Biggie Smalls for providing the graphics of the glans shapes. I can see where they do resemble most of the glans that I have ever seen. But now I know mine glans was an afterthought. It doesn't look like any of those depicted. Maybe the closest is a weird combination of 2 and 4, but the glans is thinner than the shaft. So rather than having a pronounced ridge extending beyond the glans, it just looks like a glans designed for a smaller penis that just got placed on top of my shaft. Again, I am glad my glans is hidden by my foreskin.
